NEW YORK (GenomeWeb News) – Shares of Millipore climbed as high as $102.91 — a 44 percent rise from its Friday closing price of $71.34 — after a report from Bloomberg claimed that Thermo Fisher Scientific has made an unsolicited $6 billion bid to acquire the firm.

A Thermo Fisher spokesperson said the firm would not comment on the "rumor," and Millipore did not respond to a request for comment.
